Kirino Mosaic

Omiya Shinobu has just become a first year high school student. Heading to school in an unfamiliar uniform, she finds a single piece of air mail on the counter in the entrance to her home. The sender is the daughter of the family she stayed with in middle school, Alice Cartalet!

Several weeks after arriving at Shinobu's home, Alice has grown used to life there and is enjoying her high school life in Japan. The mild-mannered and kind Shinobu. The composed but sometimes scatterbrained Aya. The bright and energetic Yoko with her monstrous appetite. Sensitive about her height and shy, Alice managed to make good friends and was spending her days happily, but...Alice beg...

As usual, Karen comes to Shinobu and her friends' classroom during lunch with bags full of snacks and bread in each hand. It seems her classmates have been gifting the items to the popular Karen. Karen is shocked when Alice asks if she's gained weight since coming to Japan.

With the new term beginning, Alice is excited until she sees the class changes and immediately begins acting absent. Alice has been put in a different class from Shinobu.Her classmate Yoko becomes worried when she is unable to cheer up Alice.
